###### Question details

1. Liam made a 3 × 3 target on a 10 × 10 dartboard.

What is the probability that a dart will hit Liam's target?

 93% 9% 3% 30%

2. Darts are thrown at random at each dartboard. Find the probability that the dart will land in the shaded region. Write your answer as a percent. ________________________

Find the probability that the dart will land in the shaded region. Write your answer as a decimal. 5.. Olivia made a 6 × 6 target on a 10 × 10 dartboard. She said that the probability of a dart landing in her target area would be twice as great as the probability that a dart will land in Liam's target area. Do you agree?

 Yes; the dartboard is identical to Liam's but scaled up by a factor of two No; Olivia’s target area will be 4 times Liam’s target area, so the hit probability will be 4 times as great Yes; the area of the target is twice as big, so the probability of a hit is twice as much No; Olivia's reasoning is not taking into account the diminished non-target area
